AT&T will pay a $4 billion breakup fee to T-Mobile's parent company

AT&T has scrapped its plans to purchase rival mobile carrier T-Mobile USA in the face of opposition from two U.S. agencies.

AT&T said Monday it has agreed to end its bid to acquire T-Mobile USA from parent company Deutsche Telekom for US$39 billion. AT&T will "continue to invest" in its services, Randall Stephenson, AT&T chairman and CEO, said in a statement.

AT&T will pay a $4 billion breakup fee to Deutche Telekom, with the charge added to the company's fourth quarter financial results. AT&T will also enter into a roaming agreement with the German carrier.
